fix(local-model): a view read while the job ends no longer shows paused

The install window polls GET /api/local-model every second. A read of the
state file that was still out while the job wrote its last state and let
go of this.job came back with the old `installing`, and settling that with
no job in the process read it as an interrupted job: `paused` with Resume
for one tick before `failed`. Under CI load this made
test/local-model-install-e2e.test.ts fail on a different failure case per
run (master 86502b69, PR #790).

currentState() now reads again when the job ended during the read. The job
writes before it lets go, so the second read has the final state.
